Applicatonled March 24, 1922. Serial No. 546,458.

To all whom "it may concer/n.'

Be it known :that I, STEFAN AMZLER, a citizen of the United States, residing at 2042 Liberty .Avenue, Ogden, inthe county of 4Weber, State offUtah, have invented a new in Crude-Oil the following is a specifiand useful Improvement Burners, of which cation. v d. Y My invention relates to that class of burner in use on railroad locomotives, sea going boats, stationary power plants, or any power plant using the hydrocarbon type of burner.

Having observed through practical demonstration that most of the burners in use are defective, in that these are made up of adjustable sections, and become warped and useless under strong heat, waste fuel, and cause delay and trouble, I have invented and made .improvements to overcome these defects bythe construction of aY crudeoil burner, consisting of two members, each being a casting in one piece, and fastenedtogether; each a part of the other, but independent of each other in function; and so designed and constructed. that it 'can be quickly installed on aV railroad locomotive?, and will fit the present standard arrangement of feed pipes and control valves without any change in the maj ority of cases. f

The top .member and main body of the burner has no movable or adjustable parts, and therefore diers materially ,from many i of the burners nowbeing made, *inA that itis cast in one piece having twocompartments, an oil' passage and asteamgpassage; these passages are again subdivided, soasfto pro: duce the fresult requiredandvperform the functions hereinoutlined. f 1 The important features of this burner, and the constructionthereof, Y will, be shown on'v theaccompanying. drawing, described and pointed out in 'detail in: this. specifica: vtion by gures, Vletters and numeralshin which: 2 i' Fig-lis a side elevation show-ing thez outlines lofthe Yburner,in upper and lower memf bers, I with internal features to be .described hereafter.- Y u i F ig.2 shows the top of theburner onV a streamline plan, spreading uniformly out to-{the front, with a hood and vent-holes to Fig. 3 is a vertical cross-section at the intake, showing location of feed pipes, hood with vent holes, straps, clamps and hinge, with intake end' of an air nozzle or blower.

Fig. 4 is a vertical and longitudinalcrosssection through the `zmainbody of they burner, showing Ythe internal construction of both `members, -with channels, passages shelves, projecting side walls, hood, feed pipes, outline topand bottom, to be particularly described hereafter.

Fig. 9 is a vertical cross-section at the p mouth or .discharge end Vof the two members, showing the relation of exits .to each other and the-relation of the1 upper member to the vlower member-the air nozzle or blower. ,.7

Now, therefore, to more particularly detine and describe this my invention, similar letters and numerals refer to similiar parts throughout the several views, in which: Y Fig; 4 is the principal view on the drawing, and is a vertical longitudinal crosssection through the middle, 'in which a is the top sloping. downward from the hood f to the mouth of the' burner,having vertical 'sidewalls' b, b, connecting top a with bottom c, provided with afuel oil passage l suppliedby a feed pipe 2, capped by a'hoodff to make room for fired pipe and vmaking-j one of the buffer shoulders e e (Figures 1,2and 4) provided with vents a, a, (Figures 1,12 and'4) to allowair to escape from the'oil passage 3 which .is divided b-va vertical wedge-shaped partition 3, -Y (Figures `4 and 5) between -ethe i middle s horizontal partition 4, vand the top',a,rseparatingrthe oil passage fromthe steam passage 5, Awhich is againdivided by a horizontal partition 67 and. a vertical partitionl (Figures 4 and.-6) .supplied by a. feedpipe 8, disf charging` at anv upward angley 9., intercept- 1122, andfreinforced .by a second atomizing steam jetv 12) r discharging .atJV an upward angle on aV vapori'zing shelf 13 which is (Fig. 4) intercepting the oil that may escape the upper jets so that no waste can take place. l i .l

The upper member of the burner here pointed out is held in place by a strap or clevis f14, (Figures 1,2 and 3 vto which the second member, an air nozzle orV blower 15 is attached with bolts 16, strap 17, nuts 18, clamp 197 on both sidesof'the burner; and further secured to the main body by hinge 20, screws 21 supplied and operated by compressed air from feed pipe 22,l discharging through channel 23 over shelf 26` at the Ymouth of'air nozzle or blower, held in place by'shoulde'r 25 (Figures 'land 3), adjusted by'block 27 on' perforated' flat 'rod"28 held in place by keys 29 (Figures 1 and Figure@ shows the `application pf the clevis l`,1'4 with bolts 32,"by"w`hich the two: membersy'are combined and fastenedt'o the fire box vand ready Yfor operation.

The object of thiseoiistruction Ahas been stated, and old principlesapplied in' anew way is .what hereV described.

The main features' will be pointed out with referencel to Fig. 4, on theaccompanying drawii'igfwhichisia vertical and;hri zontal cross-Sectioy through the center thereof. i' i By'inspection it will be seen that the top the mouth, and that the upper partis cast in one piece, widening out uniformly to the front', right and left, provided vwith two pasages, one foifuel oil 'and one for steam under pressure. The upper passage VV1 (Fig. 4') is the oil :channel andis iii two compartments, Ydivided"bya vertical wedgeshaped partitionv 3(Figure's 4`and`5) of which the headis at exit- 10 and taper ing back lto la little'wi'tliin the lfeed pipe 2, each compartment provided with bi'iffei1 shoulders e e, top andbotftoin, to control the flow, in case l'ofsudden"stops 'or jars, and prevent spitting and loss of fuel, which is one of the present defects. I have also provided a hood f to 'make room for the feed pipes 2, to 'make a Ystop against the flange of theflre box, and provided'this hood with ventV holes Wwe 2) for the release of 'air that may accumulate iii the oil 'passages and check the flow. `Each channelis provided with a downward slope ai iii@ aoor' i (Fig: 5) from ai@ mardis partition as the puter- W'aiis et b, gaat with alight feedthe oil 'will settle to each side and produce even Haine aiidheat in'v'the esta; the e@ emes disfharagfos'r a reimdedp .10 ,(Figufe t alf) .there @Qmbisen'iakes SPlace 'allowing' 110 part of the fuel'oilto' escape intothe-ash I have .found .by practical experience that thermic efiiisency dependson'the mannein which the fuel and flame is directed into the re box, and have reason to believe that dividing Ythe liquid fuel into two branches, right'ai'idY left, with Va space between, ad-

mits more air, produces better results, and

material saving of fuel.

YTo obtain this result, I have provided triple steam atomizing jets by dividing the' a greater volume of steam above than be low 'this'- partition. The upper part of this channel is'again' divided by a vertical tri-4 angular partition 7 (Figures 4 and 6) to'p'roduce adouble steam jet, one directly under each of the. exits of the o'il channel, inteicepting therv How by the steam jets and thevapoiizing shelf 11, (Figures 4, 5 and and 6),'and this is again reinforced by the lower steam jet 12 (Figures 4 and 9) and the shelf 13, leaving a space oil air passage'between the steam jets to supply the oxygen requiredy for combustion.

" With this device and construct-ion, I save a material percentage of fuel, and overcome the present waste yof oil that' isY lost by spilling into the ash pan,'which together with'the carbon residue and sand forms a slag that absorbs heat and must be removed byihaiid at considerable cost.v I' I .To overcome this last difficulty I have provided a'second member, lan air nozzle or blower, operated by" compressed air for three 'or foui` seconds at a time, when sand isv introduced into the ash pan, to be re moved by the forced draft, to cleany the iues of the boiler.

This nozzle or blower has the outline and flaring shape of the main body and 'set at an angle so that the blast will keep the sand and carbon residue in motion long renough to be. carried off by theV draft an keep the ash pan free from slag..

' Now, therefore, having described and pointed out the construction and operation of this burner,"applying old principles in a new way, simply and practically, I desire Letters Patent of the United States for the protection thereof, andA I claim:

member cast in onek piece, rectangular in cross-section, with sidewalls at right angles to the floor, diverging right and left from head to delivery, provided with a hood and converging top, from the vertical shoulder of the'h'ood to a pointAV where the sidewalls are beveled downward and meet `with ythe projecting'f'oor", having a Vpassage for liquid fuel anda passagefor 'steam under pressure,

each 'passage provided with" a 'nipple tocoii'-` neet Wth'SuPPlY Pipe, said' passages `(sepa.

41Q A crude oil burner,v consisting of a Y rated from each other by a main horizontal transverse partition, and again subdivided byhorizontal and vertical partitions, pro"- vided with passa es and exit openings, projecting shelves, sidewalls and floor.

2. A crude oil burner, including an air nozzle cast in one piece, rectangular in cross-section, having diverging walls from feed end to delivery, having a passage for compressed air, an exit opening between projecting sidewalls and over a projecting floor, a nipple to connect to feed pipe from a main supply reservoir, provided with lugs, resting in clamping straps on each side, a hinge by which this member is fastened to the burner nozzle under the floor thereof, a perfonated rod and sliding block, the whole bolted to clevis in which burner nozzle rests.

3. A crude oil burner, having an oil passage supplied by a feed pipe, a hood overy this feed pipe and over a buffer chamber, in which the inner converging shoulder forms the top, and the converging shoulder of a horizontal and transverse. partition extending from Wall -to wall forms the bottom of the buffer chamber and the floor of the oil passage, converging into a throat in said oil passage, which said oil passage is again divided into two independent passages by an irregular vertical wedge-shaped partition, the point of the wedge fa trifle within the feedpipe diverging to a head at thel exit, directly under the converging top of the main body and over a rounded lip formed by the principal partition, each passage rectangular in cross-section, diverging from throat to exi-t, having double exit openings, at least equal in area to the area of the feed pipe..

4c. A crude oil burner, having a double oil passage in the same plane, supplied by the same feed pipe, each passage provided with a buffer chamber, capped by a hood having vent holes for each chamber, said chambers converging into a throat for each passage, rectangular in cross-section, diverging with the walls of the burner, and a wedge-shaped partition between the passages, and a rounded lip extending beyond the exit openings; the outside walls projecting beyond these exit openings, a rounded lip and beveled down to the projecting floor; in which the vertical wedge-shaped partition is the inside wall for each passage and the vertical outside walls of the main body are the outside walls of said oil passages.

5. A crude oil burner, having an oil chamber provided with two exits above a main horizontal and transverse partition, a steam chamber formed between said p-artition and theJ floor of the main body of the `burner, provided with a nipple to connectV with supply pipe from a main supply reservoir, divided into upper and lower passages by a horizontal and transverse Wedgeshaped partition, the point of this wedge a trie within and a little below the center of said feed pipe, terminating at the head of the wedge in a transverse projecting corrugated shelf, the upper passage beingsubdivided by a triangular vertical partition, converging into thin apertures and exits, under the oil exits, and a rounded lip, and in line therewith, over a transverse corrugated shelf and the projecting main floor, between and enclosed by projecting sidewalls.

In testimony whereof, I have signed my name to this* amended specification at Ogden, State of Utah, this 20th day of March, 1923.
